An 18-year-old man from Hampton Park charged after being found asleep in a Donvale home has been denied bail by a Melbourne magistrate.

Isaac Henderson has been charged with burglary and threats to inflict serious injury after allegedly holding a knife to the throat of Melanie Christensen when he was disturbed while sleeping in her living room.

It is alleged he told her: “I’m going to hurt you.”

In denying bail, magistrate Marc Sargent said: “What I find disturbing was his preparedness to brandish a weapon when it was completely unnecessary.”

Part of the confrontation was recorded by Ms Christensen’s husband, Tony, on his mobile phone.

But Henderson’s lawyer, Liz Upton, argued he wielded a chicken skewer and not a knife.

She told the court Henderson was merely trying to get out of the house.

Senior Sergeant Brendan Keane admitted to the court it was a plausible explanation.

“It’s his word against hers,” he said.

Accused ‘argued with dad, got lost’

The court heard Henderson was on probation when he visited his father in Donvale.

After an argument with his father, Henderson got lost and looked for somewhere to sleep and charge his mobile phone.

He broke into the Christensens’ home through a rear window.

Outside court, Senior Sergeant Keane said it was a bizarre case and the video was pivotal to making an arrest.

Police found Henderson in the backyard of his Hampton Park home holding a dog on a chain.

The court heard Henderson told police: “I’ll put the f***ing dog onto you.”

Police said Henderson later made full admissions but denied making threats or holding a knife.

While Mr Sargent denied bail, he agreed to adjourn the matter to hear further argument.
